To all whom it may concern.- n

Be it known that I, FRANK E. MANAHAN, a

ful Improvements in Ball-Bearing Journal- Boxes, of which the followingis afull, clear,.

and exact description, reference being had to the accompanying drawings,formingrpart of this specification.

My invention relates to a journal-box inl which ball-bearin gs areutilized to reduce the friction consequent to the rotation of the axle?spindles in the box; and the invention Vconsists in features of noveltyhereinafter. fullyy described, and pointed out in the claims. y

Figure I is a side view of my journal-box applied to the truck-frame ofa railway-car. Fig. II is a vertical sectional view taken on lineII II,Fig. III. Fig. IIIis avertical section al view taken on line III III,Fig. II. Fig. IV isa vertical sectional View talen on line IV IV, Fig.III. Fig. V is a perspective View of the jou'rnalfbox shell and theremovable slide located therein. Fig. VI is a perspective viewlofthe'slide shown in FigvV. Fig. VII is a perspective view ofwlreballholding key.

A designates a portion of acar-trucl; frame, and B a car-wheel. Y Y

1 designates the aXle-spindlaprovided with a screw-thread 2 and.grooved-to; receive Va spline 3, that is heldy by a retaining-bolt 4,which passes through the axle-spindle and spline. v

5 designates the shell of the journal-box, which is of octagonal shapeand is provided with an annular inwardly-projecting flan ge 6v at itsinner end.

By the use ofa journal-box of noncircnlar shape, preferably octagonal,as shown, IV am enabled to mount the bearing member of the journal-boxseated therein in such manner as to avoid the necessity for fasteners ofany description for thepurpose of preventing rotation of saidbearingrnember in the boxshell, owing to the factlofthe interior of theshell'an'd thebearing member being of corresponding non-eircul'ar'shapethat will not permit rotation of such member. Another advantage inmaking the shell of non-circular shape lies in the fact that it affordsHat faces for the'attachment to the truck-frame, so that the shell maybeheld more firmly and 4rigidly within such frame'.

1 2ofy the axle-spindle and grooved to receive .the spline 3, bywhichsaid ring is held in a vfixed position von the spindle after it has beenAscrewed thereonto, the spline in turn being .held from displacement bythe retaining-bolt 4. The bearingvring 9 is provided with race- -ways10, in which bearing-balls l1 travel.

12` designates an outer bearing-ring provided with raceways 13,-loeatedopposite the raeeways 10 to receive the bearing-balls 11. The outerbearing-ring 12 is provided with a shouldered annular flange 14,thatprojects inwardly and bears against-a dust-ring V15, located betweensaid iiange and the inner end of the bearing-ring 9. The bearing-ring 12is retainedin place by a retaining-ring 16, that is seated within theouter end of thei shell `5 against said outer bearing-ring and'is heldin place by retaining-bolts 17, that pass through said'ring and shell. jThe outer bearing-ring 12 is Tof sectional construction, there beingpreferably-anvupper anda lower section, as seen in Figs'lland IV, thelower section of which is vadjustable withrelation to the upperseetionto compensate for the wear that mayl occur in the use .ofthejournal-box, and in order to accomplish such adjustmentl provideset-screwsilS, seated inl the shell 5 and adapted to bear againstthelower section of the outer bearing-ringfthe set-screws being equippedwith jam-nuts 19,- by which they are held when set. By inward movementof the set-screws 18 the lower-sectionofthe outer bearing-ring is movedupwardly to the -upper section-of said ring. This feature of the con-.'struetion is-also of merit in view of the fact that it provides forsufficientadjustment of the outer bearing-ring to comp'ensate'forg'reatwear thereof, inasmuch as when the bearingring has become worn'to anymaterial degree the sections may be removed and `rediiced by cuttingthem awayat the `opposite f aces of the sections, and when replacedthelower section may be adjusted with relation to the upper section toproduce the requisite adjust- IOO ment necessary for the properoperation of the bearing-balls 11 in their raceways.

In order to provide for the introduction of the bearing-balls 11subsequent to the assembling of the remainder ofthe bearing and theremoval of such balls previous to the dismantling of the bearing at anytime, I introduce a filler-block 20 between the ends of theretaining-ring 16, which ring is of broken form, as seen in Fig. IV, thesaid filler-block being held between the ends ot' the retainingring bybolts 21.

22 is a key provided with a groove 23 to receive the travel of thebearing-balls 11 and provided with tongues 24, that fit in undercutgrooves 12a in the bearing-ring 12. The key 22 is set into thebearing-ring 12 longitudinally thereot` and is held therein by thetongues 24, so that the groove in the key extends transversely of theraceways 13 in the outer bearing-ring to receive the bearingballs. Whenit is desired to insert or remove the bearing-balls, the llerblock 20 isremoved and the key 22 is withdrawn from its seat in the bearing-ring12, at which time the balls may be introduced into their racewaysthrough the space previously occupied by said key or be permitted toescape through the same space. lVhen it is desired at any time todismantle the journal-box and remove the axle-spindles therefrom, thebearing-balls are removed from the journal-box in the manner stated,after which the bearing-rings may be withdrawn subsequent to the removalof the retaining-ring 16, which is easily disconnected from the shell 5ou the withdrawal of the retaining-bolts 17. Then the retainingring hasbeen taken from the shell, theretaining-bolt 4 is withdrawn from theaxlespindle, thus permitting the removal of the spline 3 and theextraction of the inner bearing-ring f) by unscrewing it from theaxlespindle. rlhe outer bearing-ring 12 may then be slipped out of 1theshell 5, it being understood that previous to this procedure thecartruck is suitably supported by jacking it up.

In order to permit the removal of the axlespindles from the journal-boxwithout removing the journalbox shell from the truckframe, I provide aslide 25, that is movably seated in the shell 5, so that it may beremoved therefrom. The slide 25 is provided with tongues 2G, that fit inthe grooves 27 in the shell 5, and a flange 28, that is seated betweenthe flanges 2G of said shell. It is also provided with an extension 29,that seats between ears 30 on the shell and receives bolts 31, whichpass through said ears and extension and hold the slide in position, soas to complete the shell when the journal-box is in use. When it isdesired to remove the axlespindles from the journal-boxes of the car,the slides 25 are removed from the shell, and an opening is therebyproduced, through which the axle-spindles pass as the axle is lifted anddrawn away from thejournal-boxes.

I claim as my invention- 1. In a journal-box, the combination with athreaded axle-spindle, of a box-shell, an outer bearing-ring seated insaid shell, an inner bearingring having threaded connection with saidspindle, bearing-balls located between said bearing-rings, a spline bywhich said inner ring is held from rotation on said spindle, and meansfor retaining said spline, substantially as described.

2. In a journal-box, the combination with a threaded axle-spindle, of abox-shell, an outer bearing-ring seated in said shell, an innerbearing-ring having threaded connection with said spindle, bearing-ballslocated between said bearing-ring, a spline by which said inner ring isheld from rotation on said spindle, and a retaining-bolt passing throughsaid spindle and spline to hold said spline from displacement.

In ajournal-box, the combination with an axle-spindle, of a shell, anouter bearingring seated in -said shell, an inner bearingring xed to theaxle-spindle, bearing-balls located between said bearing-rings, a keyseated inA said outer bearing-ring, and a block adapted to hold said keyfrom displacement, substantially as described.
